I don't use it simply because I think it is too expensive. Without it so far this season I have shot 4 deer with my bow. I have watched on two seperate occasions 4 deer bed down within 35 yds of me (they were there over an hour each). I have also had smaller bucks and shooter bucks (after my buck tag was filled) walk around and stay in shooting range for over 15 minutes. I am not going to say that the scentlock stuff is a waste of money but I have found that it is not necessary for me.
The Gentleman speaks the truth, I would be curious to know how high he hunts in his stand. My guess he only hunts a stand when the wind is right. I have used scent-lok the last 6 years and I have a great success with it and without. I feel scent elimantion products are much better which has help. If you keep your hunting clothes clean and scent free and yourself you should be fine. I like scent-lok when I walk to and from my stand. This is where I feel I get the most benifit. Everyone has story about deer coming close to them, but its the deer we never see, are the ones I worry about. How many deer have we scared that we never seen? This is why I wear scent-lok.
